CHANDIGARH: Retired Delhi high court chief justice S N Dhingra Commission has completed the probe into land deals in Gurgaon, including the one between realty major DLF and Robert Vadra, the son-in-law of Congress president Sonia Gandhi.

"I did not issue summons to anyone except (government) officials," said Justice Dhingra, 68. He said the commission examined about 250 files related to commercial licences.

The panel heard 26 officials even as it did not ask either Vadra or IAS officer Ashok Khemka, who had cancelled his DLF land deal in 2012, to appear before it. The commission had asked ex-chief minister Bhupinder Singh Hooda to appear before it as he was the minister in-charge of Gurgaon. But Hooda's lawyer eventually appeared before the panel.
